2014 Buick Regal - Change, drain, lush, or service?

Hello,
I have a 2014 Buick Regal 4 cylinder turbo with 101000 miles. According to the owner’s manual, the transmission fluid should be changed (97500). The question I have is whether to just drain fluid, replace or service filter and refill or to get the flush also? The transmission is shifting smoothly and I have head mixed reviews about flushes.

Dont flush. Drain, replace the filter, add new fluid. Drive on.

I would change the fluid at shorter intervals. 50k miles should be good.
